If you haven't already done so, you can register your rig on the following web site and receive email notification if your model has been issued a recall. You would then have to check with Keystone to see if your serial number is included in the recall.
Keystone would mail you a notice if you're included in a recall.

Dave & Ivy,
Thanks for the link to the site to register for recalls. I signed up our rig, received the confirmation e-mail and then in about 10 minutes received notification of 2 recalls for our model year. Although neither of the recalls applied to our particular equipment, its nice to know the system does work.
